PERCOLATOR.

Patented July 16, 1907.

Application filed April 4,1907. Serial No. 366,286.

To all whom it may concern:

Be it known that I, ALONZO A. WARNER, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have in- 5 vented certain new and useful Improvements inPercolators, of which the following is a specification.

My invention relates to improvements in percolators, and the object ofmy improvement is to improve the efiiciency of the spreader upon whichthe liquid falls from the fountain tube, by a construction that compelstheliquid to pass through the said spreader in drops, no matter how fullof liquid the spreader may be.

In the accompanying drawing:-Figure 1 is a central vertical section of apercolator with my improved spreader in the drip cup, the. fountain tubeof the said percol'ator being shown in side elevation. Fig. 2 is anenlarged plan view of the spreader, and-Fig. 3 is a still furtherenlarged sectional view or a portion of the spreader on the line x ofFig. 2.

Thepercolator vessel A, its fountain tube B with connected parts, thedrip cup C and the cover D may be of any ordinary construction. In theupper part of the drip cup, above the ground coffee or other materialfor the percolator to act upon, is the spreader or retainer E. It isprovided 'with a spreader plate 4, a contral tube 5 mounted on the saidspreader plate, to receive the upper end of the fountain tubs B, andwith a raised rim 6.150, compel the liquid that falls on the spreaderplate from the fountain tube to pass through the said plate or flow overthe rim thereof.

The parts thus far described are older than the invention which is thesubject matter of this application, although as shown they are largelyof my invention."

Heretofore this and similar retainers have had their spreader plates inthe form of strainers, one form of which is shown in my Patent No.821,445, dated may, 22, 1906. In my present improvement the perforatedQrspreader phipe 4st bottom of the retainer is provided within. seriesof upwaidly projecting hello w cones 7 each of which is provided with aperforation 8 proforably at the ape as bstshown in the enlargedsectional View Fig. '3. These are formed by striking up from the metalof th s plate' i -ahd I prefer in each case to form a slightannular'riin'il'omthe under side of the spreader plate and around the base of each hollow cone to prevent a lateral flow of the liquid.

In a percolator of'the above construction the liquid that falls or! thespreader plate within the retainer or spreader, works through theperforations 8, collects within the hollow cones and falls therefrom inlarge drops and never in a continuous stream, no matter how full theretainer may be. In view of this fact, the rim or overflow 6 around thecdgo of my spreader plate may be made higher than heretofore, because abody of liquid on the top of the plate does not cause the liquid todischarge in streams. The ordinary spreader plates ,With a simplestrainer are made shallow so that they cannot contain such a depth ofliquid as would increase the tcndencyto force the liquid through theplate in streams. The hollow cones also act to separate the dischargefrom the different perforations, so that the discharge from two or moreperforations will never unite on the undor side of the plate, as thatfrom several perforations will run together on the underside of aspreader plate having a simple strainer, as in my aforcsaid patent. Thepercolating effect of the liquid thus falling in drops upon the ground'cot'fec or other material in the drip cup, is believed to be moreefficient than would be the same amount of liquid passing therethroughin a continuous stream, besides distributing the material over a largersurface of the spreader plate than it would be distributed if the liquidpassed through in a stream or streams. It also distributes the liquidmore evenly than it can be distributed when the discharge from severalperforations run together on the underside of tho spreader plate beforefalling, no matter whether it falls in drops or streams.

I claim as my invention:

1. In a pcrcolutor, the coulbluutlou of u drip cup and fouutuin [.ubowlth a retainer or spreader lluvlng sprcudor plate in lho upper part ofthe drip cup to receive the lluuld that falls from the fountain tube,the said sproudor plate having a series of. upwardly projecting hollowcones, performed to admit the liquld lnto'the lulorlol ol the soldhollow cones.
